Note: Effect of TVC, TCE, and SNS on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. TVC = talking on the phone, videochatting; TCE = texting, chatting, emailing; SNS = interactions on social networking sites; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of TCE, SNS, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: TVC with close peers). Shown are unstandardized estimates with 95% credible intervals in square brackets. TVC = talking on the phone, videochatting; TCE = texting, chatting, emailing; SNS = interactions on social networking sites; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction), including episodes with multiple partners. Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties (reference category: no social interaction), including episodes with multiple partners. Shown are standardized estimates with 95% credible intervals in square brackets. Meta-analytical results are based on a linear fixed-effects meta-analysis of the individual estimates from the three samples. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with two-tailed p < .01.

Note: Effect of friends and roommates, significant others, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Friends and roommates = interactions with friends and/or roommates; Significant others = interactions with significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, significant others, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: FtF interactions with friends and roommates). Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Friends and roommates = interactions with friends and/or roommates; Significant others = interactions with significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of social interactions on stress in S1, S2, and S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Social interaction = any kind of social interaction; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of FtF interactions, CMC, and mixed episodes on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of FtF interactions, CMC, and mixed episodes on contentment in S1 and S2 and happiness in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of FtF interactions, CMC, and mixed episodes on stress in S1, S2, and S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on contentment in S1 and S2 and happiness in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on stress in S1, S2, and S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on loneliness in S1, S2, and S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on worries in S3 (reference category: no social interaction). Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on well-being in S1 and S2 and affect balance in S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on contentment in S1 and S2 and happiness in S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on stress in S1, S2, and S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on contentment in S1 and S2 and happiness in S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on stress in S1, S2, and S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on anger in S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on worries in S3 reference category: FtF interactions with close peers. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on well-being and affect balance (reference category: FtF interactions with close peers). Shown are standardized estimates with 95% credible intervals in square brackets. Meta-analytical results are based on a linear fixed-effects meta-analysis of the individual estimates from the three samples. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with two-tailed p < .01.

Note: Effect of social interactions on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction), controlling for demographic variables. Shown are unstandardized estimates with 95% credible intervals in square brackets. Social interaction = any kind of social interaction; Gender: 0 = male, 1 = female; Ethnicity: 0 = Anglo/White only, 1 = Non-Anglo/White, multi-ethnic; SES: 0 = less than some college, 1 = at least one parent completed some college; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of FtF interactions, CMC, and mixed episodes on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction), controlling for demographic variables. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Gender: 0 = male, 1 = female; Ethnicity: 0 = Anglo/White only, 1 = Non-Anglo/White, multi-ethnic; SES: 0 = less than some college, 1 = at least one parent completed some college; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of close peers, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: no social interaction), controlling for demographic variables. Shown are unstandardized estimates with 95% credible intervals in square brackets. Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; Gender: 0 = male, 1 = female; Ethnicity: 0 = Anglo/White only, 1 = Non-Anglo/White, multi-ethnic; SES: 0 = less than some college, 1 = at least one parent completed some college; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Effect of CMC, mixed episodes, family, and weak ties on well-being in S1 and S2 and affect balance in S3 (reference category: FtF interactions with close peers), controlling for demographic variables. Shown are unstandardized estimates with 95% credible intervals in square brackets. FtF = face-to-face interactions; CMC = computer-mediated communication; Mixed = mix of FtF and CMC; Close peers = interactions with friends, roommates, and/or significant others; Family = interactions with family members; Weak ties = interactions with classmates, co-workers, and/or strangers; Gender: 0 = male, 1 = female; Ethnicity: 0 = Anglo/White only, 1 = Non-Anglo/White, multi-ethnic; SES: 0 = less than some college, 1 = at least one parent completed some college; WP = within-person; BP = between-person; E = extraversion; A = agreeableness; C = conscientiousness; N = neuroticism; O = openness. All models were estimated in Mplus using the Bayesian estimator with uninformed priors. Coefficients in bold are significant with one-tailed p < .005.

Note: Shown are simple slopes for two levels of neuroticism: 1 SD below the mean (low) and 1 SD above the mean (high). The plot was generated in a pooled data set, which included data from all three studies (participants N = 2,533, observations N = 120,973). Due to the differences in scales across studies, well-being was z-standardized before merging the three data sets (max = 1.5, min = -3).

Note: Results of a Monte Carlo power simulation for the power to detect small (standardized coefficient = 0.10) within-person and between-person effects of social interactions on well-being and a small cross-level interaction effect between personality and social interactions in the prediction of well-being. Number of samples = 1,000; Level 2 sample size = 3,075 participants; Level 1 sample size = 45 observations per participant.

We conducted a Monte Carlo power simulation to calculate the power we had to detect small (standardized coefficient = 0.10) within- and between-person effects of social interactions on well-being and a small cross-level interaction effect between personality and social interactions in the prediction of well-being. A standardized within- or between-person coefficient of 0.10 indicates that social interactions explain 1% of the within- or between-person variance in well-being, respectively. A standardized cross-level interaction effect of 0.10 indicates that personality explains 1% of the random slope variance of social interactions predicting well-being.

The parameters for the population model were generated as described in Arend & Schäfer (2019):

1. To obtain realistic estimates of the variances and covariances, we created a pooled data set and specified (a) a null model in which we estimated the unconditional variances of social interactions and well-being (i.e., without predictors), and (b) a random intercept-random slope model for the within-person relationship between social interactions and well-being, in which we estimated the unconditional random slope variance (i.e., without the cross-level interaction effect). From the null model, we derived the within- and between-person variances of well-being (within: 0.583, between: 0.431) and social interactions (within: 0.173, between: 0.053). From the random intercept-random slope model, we derived the random slope variance (0.048) and the random intercept-random slope covariance (-0.036). The mean of personality was set to 0 and the variance was set to 0.589 (variance of neuroticism in the pooled data set). The Level 2 mean of social interactions was set to 0.690 (adapted from the null model) and the Level 2 intercept of well-being was set to -0.200 (expected value for a person who never interacts if the overall mean is 0).

2. We adjusted the standardized coefficients to the scales in the empirical data set using the following equation:
   standardized coefficient * sd outcome / sd predictor (see Equation 15 in Arend & Schäfer, 2019).
   This resulted in the following parameters for the simulation:
   Level 1 effect (Int -> WB): 0.10 * sqrt(0.583) / sqrt(0.173) = 0.184
   Level 2 effect (Int -> WB): 0.10 * sqrt(0.431) / sqrt(0.053) = 0.285
   Level 2 effect (P -> WB): 0.10 * sqrt(0.431) / sqrt(0.589) = 0.086
   Cross-level interaction effect (P -> S): 0.10 * sqrt(0.048) / sqrt(0.589) = 0.029

3. We adjusted the residual variances of well-being and the residual variance of the random slope to account for the variance explained, as described by Arend & Schäfer (2019). Specifically, the residual variances were estimated as:
   Residual variance WB within: 0.583 * 0.99 = 0.577 (1% of the variance explained)
   Residual variance WB between: 0.431 * 0.98 = 0.422 (2% of the variance explained)
   Residual variance slope: 0.048 * 0.99 = 0.048 (1% of the variance explained)

Based on these input parameters, we generated 1,000 samples (level 2 sample size = 3,075 participants, level 1 sample size = 45 observations per participant; total number of observations = 138,375) and determined the proportion of samples in which the estimates were significant (alpha = 0.05). The results indicated that we had 100% power to detect small within- and between-person effects of social interactions on well-being and 93% power to detect a small cross-level interaction effect between personality and social interactions in the prediction of well-being.
